VIDEO: Julianne Moore cast in The Hunger Games

Kristyn Burtt is an IAWTV award-winning host and entertainment reporter. She currently hosts the recap shows for "Dancing With the Stars" and "So You Think You Can Dance" on AfterBuzz TV and for "True Blood" on GeekNation.

Moore will play President Alma Coin in two films, The Hunger Games: Mockingjay, Parts 1 and 2. Her character is the head of the rebel forces fighting against the Capitol of Panem, and she is often found battling with the main character, Katniss Everdeen, in the story.

The actress shared her excitement about the role with her followers on Twitter.

The juicy role in the franchise will be a bit of a departure for Moore, who is better known for playing Sarah Palin in HBO's Game Change last year, her recurring role on 30 Rock and on the big screen in The Kids Are All Right.

While the films have made worldwide stars out of Jennifer Lawrence, Josh Hutcherson and Liam Hemsworth, there will be several newcomers to the final films. Evan Ross, Stef Dawson, and Game of Thrones star Natalie Dormer will be joining the cast.

Author Suzanne Collins' creation has generated hundreds-of-millions of dollars at the box office. The first movie earned $691 million globally. The second installment, The Hunger Games: Catching Fire, is expected to be the box office hit of Thanksgiving weekend later this year.

The third and fourth movie installments of the best-selling books will be released in Nov. 2014 and Nov. 2015.
